« VW Type-2 LateBay BUS
155. Blazecut
154. Fuel sending unit
The movement of the fuel gauge became unstable, and sometimes the needle fell down to the left end. I kept running for a while, and after refueling, it returned to normal, but when the memory reading about 1/4, it suddenly fell down to the left end. This behavior was consistently reproduced.
I checked the wiring on the back of the meter and the resistance to prevent blurring, but it seemed to be fine, so I guessed that it was probably the fuel sending unit. However, in order to replace it, it was necessary to unload the engine and remove the tank, so I asked the special shop "SILVER REST" that takes care of my BUS.
Correlation between actual remaining amount and memory. I made an illustration based on the photo of the meter I received.
This image is a combination of product photos borrowed from the FLAT4 website. This time we adopted this. It has a different shape than before.
There was VDO lettering on the rim of the lid and on the side of the float. Is there a VW mark if genuine?
The contact on the left arm (the round part at the top) slides along the arc of the coil to change the resistance value.
This is the taken out fuel sending unit.
The left is the tank and the right is connected to the fuel filler port. The opening on the right side is close with a round lid.
The new hose is in front. There were countless cracks on the outside of the hose I had been using.
A small hole in the tank seems to be a gasoline passage.
When I took it apart, We found that the end of the wound coil, the coil around where it was when the fuel was filled, was broken.
Remove the fuel sending unit from the tank.
The engine was lowered and the tank extracted.
This photo was taken when I went to pick it up.
